Normally I expect the apartments to be smaller than they appear in the pictures, but this place was the opposite. It's absolutely huge and very clean. It's also quiet as it's tucked away in a small side road. There's air-conditioning (also very quiet) in every room which is a godsend in the Bangkok sweltering heat. The bed in the master bedroom is also really big and we slept very well at night.
The location is great, next to the famous part and very close to the underground.
However, describing the apartment as luxurious is a big stretch. It's quite dated and in need of a refurbishment. The kitchen is particularly tired and basic and didn't really inspire us to cook. However, the bathrooms are top spec with excellent water pressure.
We didn't have much communication with Phannivat but the little that we discussed before we got there, he seemed warm and welcoming. He had also left bottled water and some snacks waiting for us, which was much appreciated and a lovely touch.
